I have a question about leaving a hot tub while going on vacation. What does everyone do with there chemicals. It seems that I normally add about 1-2 oz of chlorine every night after checking with test kit to get my level back up to around 7ppm of FC. If I were to go away for a few days or a week what do I do while I’m gone. Is there a floater I can use? Just looking for some suggestions. Thanks in advance
